Question

我试图测试以下服务，似乎无法匹配模拟响应：

public getCustomerDetails(customerID:string): ng.IPromise<ICustomerDetails> {
    return this.testService.getCustomerDetails(customerID).then((customerResponse:ICustomerResult) => {

        var customer = customerResponse.customers;

        var customerDetailsResult:ICustomerDetails = {
            customerNumber: customer.displayCustomerNumber,
            name: customer.name,
            userId: customer.buId,
            customerType: customer.type,
            address: customer.displayAddress
        };

        return customerDetailsResult;
    });
}

这是Jasmine代码：

describe('CustomerService', () => {
    var mockTestService: any = {};
    var $q: ng.IQService;
    var createCustomerDetailsService;
    var customerDetailsService;
    var createResolvedPromise;
    var resolvePromises;

    var serviceResponse = {
        customerNumber: 'string',
        name: 'name',
        userId: 'buId',
        customerType: 'type',
        address: 'displayAddress'
    };

    var rootScope;

    beforeEach(() => {
        module('app.customer');

        inject(( _$q_, $injector) => {
            this.$q = _$q_;
            rootScope = $injector.get('$rootScope');

            createResolvedPromise = (result) => {
                return this.$q.when(result);
            };

            resolvePromises = () => {
                rootScope.$apply();
            };

            createCustomerDetailsService = () => {
                return new app.customer.CustomerService(
                    mockRnsService);
            };
        });

    });


    it('WILL search by customer ID and return a customers details', () => {
        var searchResponsePromise;

        mockTestService.getCustomerDetails = jasmine.createSpy("getCustomerDetails").and.callFake(createResolvedPromise);
        customerDetailsService = createCustomerDetailsService();
        searchResponsePromise = customerDetailsService.getCustomerDetails('12345678');
        resolvePromises();

        expect(searchResponsePromise).toEqual(serviceResponse);
    });

});

我得到的错误是：

TypeError: 'undefined' is not an object (evaluating 'customer.displayCustomerNumber')

有谁能告诉我为什么我会收到此错误？谢谢你的帮助。

createResolvedPromise设置getCustomerDetails以使用您传入的参数值返回一个承诺 - 在本例中为'12345678'。这意味着customerResponse的值为'12345678'。因此，customer从customerResponse.customers获取值的customers未定义，因为字符串上没有属性customer.displayCustomerNumber。因此，当您尝试评估customer时会发生错误，因为CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; animation.repeatDuration = 1000; animation.duration = 30; animation.additive = YES; animation.removedOnCompletion = NO; animation.fillMode = kCAFillModeBoth; animation.fromValue = [NSNumber numberWithFloat:0]; animation.toValue = [NSNumber numberWithFloat:360]; [self.SearchButton.layer addAnimation:animation forKey:@"rotationAnimation"]; [CATransaction begin]; { [CATransaction setCompletionBlock:^{ [UIView animateWithDuration:0.6 delay:2 options:UIViewAnimationOptionCurveEaseIn animations:^{ [self.SearchButton setFrame:CGRectMake(self.slideMenuButton.frame.origin.x, self.slideMenuButton.frame.origin.y, self.SearchButton.frame.size.width, self.SearchButton.frame.size.height)]; [UIView animateWithDuration:0.6 delay:10.f options:UIViewAnimationOptionCurveEaseIn animations:^{ [self.navigationController presentViewController:Search animated:YES completion:nil]; }completion:^(BOOL finished) { [self.SearchButton setFrame:CGRectMake(searchOrigin.x, searchOrigin.y, self.SearchButton.frame.size.width, self.SearchButton.frame.size.height)]; }]; } completion:^(BOOL finished) { [self.SearchButton.layer removeAnimationForKey:@"rotationAnimation"]; }]; }]; }未定义。

使用Typescript进行Jasmine + Angular测试：TypeError：＆＃39; undefined＆＃39;不是一个对象
